The Vampire Diaries

The Vampire Diaries is an American supernatural–fantasy horror/drama television series developed by Kevin Williamson & Julie Plec, based on the book series of the same name by L. J. Smith. The series follows the life of 17-year old Elena Gilbert (Nina Dobrev), who falls in love with a centuries old vampire named Stefan Salvatore (Paul Wesley) and his brother Damon Salvatore (Ian Somerhalder), also a vampire. As a result, this draws Elena and her friends into the supernatural world of Mystic Falls, where it is plagued by vampires, werewolves, witches, doppelgängers and Original Vampires.

The Night Hunters has some similar monsters and nature as The Vampire Diaries-universe, but it is not as similar to it, as Supernatural.
